OPEN TEXT OR IMAGE OR VIDEO FILES VIA TERMINAL IN LINUX

Hi There!


Have you ever thought of how to open Text or Image or Video files in Linux OS via Terminal (Command Line Interface)?


If you know, then you are the best.

If you aren't, you are not bad. Come, Let us know about that.


Open Terminal.

Go to the path where the respective file exits.
For ex 'jeevagan@jeeva-pc:/home/iprotecs/Videos' (where I tried here to open a video file)

Type 'xdg-open Facebook.mp4' and hit Enter. (where Facebook.mp4 is a filename here)

This will open the entered file name with the default video playing application.

If you want to open that video file via VLC player, install the VLC player first and then go to the path where the video file exits and type 

# vlc "Facebook.mp4"

 and hit Enter.

That's it. xdg-open will open the file with default application, where 'application <"Filename.extension"> will open the file with our own desired format.

Thanks,

Jeevagan Nagarajan.

TOP 10 PEOPLE WHO CHANGED THE WORLD


Top 10 people who changed the world .....

1. Bill Gates :
Bill Gates created his first computer program while still at high school, co-founded Microsoft in 1977, and by 1993 was the richest man on Earth. In 2000 Gates and his wife formed the Bill & Melinda Gates foundation, which is the largest charity in the world. One of its aim is to exempt the Third World of polio and other deadly diseases.

2. Martin Luther King :
Martin Luther King was a Baptist minister who campaigned against the segregation of blacks in the Southern states of the United States. He was influenced by Gandhi and believed in peaceful protest. He won the Nobel Peace Prize in 1964. King was assassinated in 1968, but will always be remembered for his dignified, passive resistance to an unjust society.

3. Nelson Mandela :
Nelson Mandela dedicated his life to the fight against apartheid – a policy which kept black and white South Africans apart and denied black citizens the vote. He was imprisoned in 1964 for his aggressive opposition to South Africa’s racist government and was held for 26 years. In 1990, after his release, Mandela was elected President of the African National Congress. In 1993 he won the Nobel Peace Prize for his work to end apartheid

4. Adolf Hitler :
Adolf Hitler was Germany’s leader from 1933 – 1945, during time which he led the world into the most devastating war in history. Hitler’s hatred of Jewish people and his desire for a blue-eyed, blond-haired master race led to the murder of six million people during World War II; most died in concentration camp in Eastern Europe.

5. Albert Einstein :
Albert Einstein was one of the greatest of all physicists and his name has become a symbol of genius. When his most famous work, the General Theory Of Relativity was proven in 1919, Einstein became the most celebrated scientist in the world and he won the Nobel Prize for Physics in 192 1. Einstein was a firm believer in pacifism but his scientific theories helped his adopted country, the USA, to develop the atomic bomb. A week before he died Einstein wrote to Bertrand Russell, a British Philosopher and leading antinuclear campaigner, asking to put his name to a manifesto urging all countries to give up their nuclear weapons.

6. Mahatma Gandhi :
Gandhi began his career as a lawyer but became a great political and spiritual leader. He led the peaceful civil disobedience of Indians against British rule in India and negotiated with the British Government until 1947, when India was granted independence. Gandhi became the first icon of a people’s struggleagains oppression. His simple lifestyle and his belief in religious tolerance have made him a symbol of decency and peace ever since.

7. Karl Marx's :
Karl Marx's ideas on economic history and sociology changed the world. Marx was a social philosopher who attacked the state and predicted a future in which everyone was equal. He explained his theories in the Communist Manifesto (compiled with Friedrich Engels and published in 1848) and Das Kapital (1867 – 94). His ideas eventually led to the Russian Revolution and communism. By 1950 almost half of the world‘s people lived under communist regimes.

8. Charles Darwin :
Naturalist Charles Darwin established the theory of evolution. He began forming his ideas when he served as official naturalist on a world voyage on HMS Beagle (1831 – 36) and spent the rest of his life back in England developing them. When his famous book The Origin of Species by Means of Natural Selections was published in 1859, there were violent reactions against it. Darwin challenged the Bible’s account of creation and explained that human being are descended from an ape-like ancestor. Another English naturalist, Alfred Russell Wallace, independently developed very similar ideas at the same time as Darwin.

9. William Shakespeare :
William Shakespeare is generally agreed to be the greatest play writer in the English language. He began as an actor and wrote atleast 154 love poems and 37 plays, including Hamlet, King Lear, Romeo and Juliet and Macbeth. Shakespeare also probably introduced more than 1,700 new words to the English Language.

10. Christopher Columbus :
Christopher Columbus is one of the most famous of all explorers. He believed he could reach Asia by sailing west across the Atlantic Ocean and in 1492 he set sail in the Santa Maria to prove his theory. Instead, he landed on the islandsnow known as the West Indies. His discoveries led to the European explorations and settlement of the Americas.

How Could You Speed-Up Your PC??


Windows PCs typically slow down as applications are installed and used.  Whether using word processing, excels, internet, gaming or whatever stuffs, hard drives fill with temporary files that do not always get removed when no longer needed. Read on to learn of ways to help keep a PC running smoothly with little or no money.


STEPS:

1. Stop all unused applications The taskbar is on the bottom edge of the screen. In the right side of it appears a group of small icons, collectively names as 'System Tray'. Each of these icons represent specific program that has been partially or running in the background. It acquires some memory and processing power.

  • Winkey+R
  • type 'msconfig'
  • click on 'startup' tab
  • uncheck all the unused or not relevant programs as shown above

2. Turn off unneeded Desktop Features that try to make things look better.




You can get these by right-clicking on 'My computer'->properties and do it as shown above. In the last dialog box, choose 'Adjust for best performance' and do it yourself as 'custom'.

3. Do a shut down/ reboot Some programs do not release memory properly when they close, which is the case for some operating systems. The computer has to be completely shut down and then restarted. Shutting down the system will have the operating system forget which memory locations aren't free, so on the next boot, all memory locations are free to use.

4. Empty the Recycle Bin Simply deleting files from the disk does not really delete them at all, rather they are moved to a temporary holding on drive for restoration. 


Once empties, the space on the hard drive that the data occupied is made available for reuse and the restoration of any files empties from the recycle bin becomes extremely difficult.  Note that this will only speed up you pc if the hard drive is nearly full.

5. Uninstall all applications that are no longer need When applications and games are installed to a Windows PC, some files are written in the Windows directory. Most of these changes are not readily apparent to the user, so proper removal requires uninstalling the program by clicking on Control Panel-> Add or Remove programs-> Uninstall programs

6. Run 'Error Checking' Right click a drive icon in 'My Computer' and select 'Properties  followed by 'Tools'. Choose 'Error Checking' to let the utility scan the drive for damaged files that can contribute to slow drive access speeds. This may take several minutes to complete.

7. Install anti-virus and keep it updated Today, anti-virus is an absolute must. There are many from which to choose at the software store, but there are free Anti-virus available that do a very good job. I would suggest Avast, BitDefender and Eset programs. Install 'Adblock' extension to your browser which prevents malware sites but also reduces temp disk space for the browser by about 30% by not downloading advertising.

8. Find and Delete temporary files Temporary files are used for supporting some applications for a limited period of time and left unused for later. You can delete it by doing this:

  • Winkey+R
  • type 'temp'
  • select all and 'Shift+del' it.
  • if it prompts for 'skip', click on skip.
  • Winkey+R
  • type '%temp%'
  • select all and 'Shift+del' it.
  • if it prompts for 'skip', click on skip.
9. Set your computer;s energy setings to High Performance This is especially true in Laptops and Netbooks where the processor speed is altered in accordance to energy settings(and if you are running on battery power)

10. Have a High RAM If your RAM is small in memory, Your PC won't support a high-speed performance. Upgrade your RAM for better performance.
